Question

The radius of void in a closed packed tetrahedral is :

• A. $0.414\times r_{sphere}$
• B. $0.225\times r_{sphere}$
• C. $0.02\times r_{sphere}$
• D. none of the above

Answer 1

Answer: (B)

$0.225\times r_{sphere}$

For tetrahedral, $\frac{r_{void}}{r_{sphere}}=0.225$

Hence, the radius of void in a closed packed tetrahedral is $0.225\times r_{sphere}$.
